Evaluation of sampling methods used to estimate irrigation pumpage in Chase, Dundy, and Perkins counties, Nebraska
F.J. Heimes, R. R. Luckey, D.M. Stephens
1986, Water-Resources Investigations Report 86-4092
Combining estimates of applied irrigation water, determined for selected sample sites, with information on irrigated acreage provides one alternative for developing areal estimates of groundwater pumpage for irrigation. The reliability of this approach was evaluated by comparing estimated pumpage with metered pumpage for two years for a three-county area in...
Water resources of Hughes County, South Dakota
L.J. Hamilton
1986, Water-Resources Investigations Report 84-4195
Three major glacial-drift aquifers consisting of outwash sand and gravel underlie Hughes County, 784 sq mi of plains incised by the outwash-filled valley of the Missouri River in central South Dakota. Glacial-drift aquifers are recharged by more than 9,000 acre-feet of water annually and store about 1 million acre-feet of...
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, east part of the Raymond Peak Roadless Area, Alpine County, California
M.A. Chaffee
1986, Miscellaneous Field Studies Map 1365-D
The Raymond peak Roadless Area consists of two separate units.  The west part (5985), about 12 miles southwest of Markleeville in Stanislaus National Forest, has been studied separately as part of the Mokelumne Wilderness and vicinity (McKee and others, 1982).  The east part (4985) is discussed here....
Hydrogeology and simulation of water flow in strata above the Bearpaw Shale and equivalents of eastern Montana and northeastern Wyoming
W. R. Hotchkiss, J. F. Levings
1986, Water-Resources Investigations Report 85-4281
The Powder River, Bull Mountains, and Williston basins of Montana and Wyoming were investigated to understand the geohydrology and subsurface water flow. Rocks were separated into: Fox Hills-lower Hell Creek aquifer (layer 1), upper Hell Creek confining layer (layer 2), Tullock aquifer (layer 3), Lebo confining layer (layer 4), and...
Assessment of low-flow water quality in the Du Page River, Illinois
W.O. Freeman, A.R. Schmidt, J. K. Stamer
1986, Water-Resources Investigations Report 85-4344
The relations of several stream processes to concentrations of dissolved oxygen and other constituents during low-flow periods were evaluated for a 70.3-mile reach of the Du Page River in northeastern Illinois, using measured data and computer simulations. Reaeration rates and traveltimes were measured at various flow rates using a steady-state...
Hydrologic reconnaissance and summary of existing data on surface and ground-water resources in the Missouri River valley in Woodbury and Monona counties, Iowa, 1985
R.C. Buchmiller
1986, Open-File Report 86-144
A hydrologic reconnaissance of the Missouri River valley in western Iowa was begun in 1985. The study area is about 400 sq mi of Missouri River flood plain used mainly for agricultural purposes and is located mostly in parts of Woodbury and Monona Counties, Iowa. The reconnaissance was conducted to...
Potentiometric surface of the upper Floridan Aquifer, west-central Florida, September 1986
B. R. Lewelling, Roger G. Belles
1986, Open-File Report 86-603
A September 1986 potentiometric surface map of the Upper Floridan aquifer in west-central Florida depicts water levels for the annual high water level period. Water levels in most wells measured in September 1986 were higher than in May 1986. September levels averaged about 1 foot higher than May levels in...
Hydrologic characteristics of soils in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, and Texas
Jack T. Dugan
1986, Hydrologic Atlas 678
Certain physical characteristics of soils, including permeability, available water capacity, thickness, and topographic position, have a definite effect on the hydrology of an area. They control the rate at which precipitation infiltrates or is transmitted through the soil, and thus they have a significant role in determining the rates both...
